Just look at how grown up she handled meeting baby daddy Ryan Edwards' new boo during Monday night's all-new episode!!!

While Maci and Taylor McKinney have been happily married for a little over a month now IRL, on the show, they're still only in the invitation stages of wedding planning — with a guest list including Ryan, Tyler Baltierra, and Catelynn Lowell so far.

But luckily for Bentley, that meant getting to spend time with both his mom and dad as well as their significant others while Ryan introduced his new girlfriend Mackenzie Standifer to his ex!

Had this been Farrah Abraham or Amber Portwood's plotline, we could imagine such a meeting resulting in police interference — but believe it or not, Maci actually likedMac-z… even going as far as calling her "cool."

As we previously reported, Britney Spears' baby daddy has requested an increase in his $20K a month child support stipend. While it's said that Godney isn't THRILLED at the request, she's letting her poppa negotiate a deal with KFed.

And it appears that negotiations are well under way, though Mr. Spears is NOT impressed with his former son-in-law!
